RFC 9851
Title: TLS 1.2 is in Feature Freeze
Author: R. Salz,
N. Aviram
Status: Proposed Standard
Stream: IETF
Date: July 2026
Mailbox: rsalz@akamai.com,
nimrod.aviram@gmail.com
Pages: 5
I-D Tag: draft-ietf-tls-tls12-frozen-08
URL: https://www.rfc-editor.org/info/rfc9851
DOI: 10.17487/RFC9851
Use of TLS 1.3, which fixes some known deficiencies in TLS 1.2, is growing. This document specifies that no changes will be approved for TLS 1.2 outside of urgent security fixes (as determined by TLS Working Group consensus), new TLS Exporter Labels, and new Application-Layer Protocol Negotiation (ALPN) Protocol IDs. This applies to TLS only; it does not apply to DTLS (in any DTLS version).
This document is a product of the Transport Layer Security Working Group of the IETF.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and
suggestions for improvements. Distribution of this memo is unlimited.
